The regiment was formed in February 1864, at
Chambersburg, Pennsylvania, by the consolidation of two battalions, the Ringgold Cavalry and a
battalion raised during the
Gettysburg campaign. The seven companies were mostly raised in
Washington County.
Jacob C. Higgins was selected to serve as
colonel, A. J. Greenfield as
lieutenant colonel, and George T. Work, Elias S. Troxell, and Henry A. Myers as
majors. The 22nd Pennsylvania Cavalry was sent to Maryland for training, after which it was assigned to the
Department of West Virginia. The dismounted men were assigned to the Reserve Division, while the mounted portion of the unit became part of the 2nd Brigade, First Cavalry Division. A detachment of the regiment, under the command of Major George T. Work, fought in the
Battle of Moorefield on August 7, 1864. The regiment fought in several skirmishes during
the Lynchburg Campaign and
Early's Raid on Washington. In August, it was assigned to the
Army of the Shenandoah as part of the 3rd Brigade, Cavalry Corps. It fought in several battles of Sheridan's campaign, such as at the
Battle of Opequon and the
Battle of Cedar Creek. In December, it was sent back to the Department of West Virginia, where it spent the remainder of the war chasing down
guerrillas. On June 24, 1865, it was consolidated with the
18th Pennsylvania Cavalry to form the
3rd Pennsylvania Provisional Cavalry. ==Casualties==
